NOTES ON LIFE-HISTORIES, LARVH, ETC. 131 
on gooseberry, and red and black currant bushes, in an old neglected 
garden in this city. Judging from the denuded bushes there must 
have been a large number of larve, most of which had disappeared. 
Amongst those left there were a few which appeared to be from three- 
fourths to nearly full-fed. I took eight of these and placed them in a 
breeding-cage in a cold room, no fire, giving them such scanty food as 
IT could. Three of the larvee pupated between November 7th and 10th; 
one of the resulting imagines emerged on December 7th, 1899, the 
other two on January 2nd, this year. The first was a male, and the 
others females—all were small and rather darker than the type, though 
not sufficiently so, to be of any use as varieties—the rest of the larve 
are still hybernating.—T. Mapprson, F'.E.8., South Bailey, Durham.

EMERGENCE oF StauRopus Faci In NovemBer.—It may be well here to 
note that in November last, two imagines of Stawropus fagi emerged 
from pup of the year.—R. B. Rosertson, Forest View, Southborne 
Road, Boscombe. 
HiRRATIC EMERGENCE OF DOMESTICATED SPILOSOMA LUBRICIPEDA VAR. 
RADIATA.—Late in October and durine November last I bred a few 
specimens of Spilosoma lubricipeda var. radiata. The emergence of 
this species in confinement appears to be very erratic, as from a brood 
of eges hatching in early June about half the brood emerged in 
August, a few, as already noticed, in late autumn, whilst the remainder 
are now in pupa, and will probably emerge in the spring.—A. W. 
Mgra, 79, Capel Road, Forest Gate, HK. 
Hastrs or Poxrcrocampa poputi.—Poecilocampa populi is not 
uncommon in the larval state at Bishop’s Wood, near Selby. I have 
found it singly in the daytime whilst searching for insects at rest, 
usually, then, in the cracks of the bark of oak and poplar. Searching 
in early June, 1896, I found eight or more larvee on the trunks; they 
appear to be nocturnal feeders, commencing to move before twilight 
(at least they did so in captivity) and eat oak, sallow, poplar, &c. 
Feeding them in a large flower-pot, they pupated during the third 
week of June, on the side just above the earth, using some of the light 
soil to form the cocoon, which, when completed, was of an earthy 
colour, mixed up with fine particles of the pot on which the cocoons 
were built. Unfortunately I lost three of the cocoons, but the four I 
had left had all produced imagines by November 8th, and were all 
beautifully marked females. I once took an imago at light at Sand- 
burn, and frequently also at the lamps in this city.—S. Waker, F.E.S., 
15, Queen Anne’s Road, York. April 27th, 1900. 
Kees or Leprmorrera.—Hrebia ceto.—A single egg laid at the 
junction of a small lateral leaf-bearing stem with a larger shoot of 
? Vaccinium myrtillus. It is of large size about 1mm. along vertical 
axis by ‘9mm along horizontal axis. The horizontal section is circular, 
the vertical one a short oval, flattened so much at top, base, and sides, 
that it might almost as correctly be called the section of a cylinder. It 
is almost equally flattened at base and micropylar ends, but is a trifle 
flatter and broader at base. There are seventeen coarse, roughly 
marked, longitudinal ribs, but they are wanting in clearness and 
sharpness of sculpturing, and give an impression of a fading, or not yet 
fully developed character. Faint traces of cross ribbing can be dis- 
cerned (with 1’’ objective), they show clearest on ridge of longitudinal
